This circuit was published in an 80's American documentation, but it is still current. The power depends on the operational. The generated signal has a sinusoidal waveform.
This circuit generates a pulse of approximately 1 second when the light incident on the sensor...
We found this powerful amplifier that uses common transistors in a 1998 documentation. The power...
This circuit is from 1994 documentation. It consists of a control for several DC motors that are...
